RUB BER-TIRE-SETT ING MACHINE.

SPECIFICATION forming part of Letters Patent No. 698,446, dated April29, 1902. Application filed July 31,1901. Serial No. 70,403. (No model.)

ber vehicle-tires having embedded longitudinal wires in channeledmetallic tires mounted on vehicle-wheels.

The objects of my invention are to provide improved means for'sustaining the wheel during the process of setting the tire, to adapt the machineto be used with the wheel in either a vertical or horizontal position,to provide new and improved devices for drawing the wires, and toprovide an adjusting device to equalize their tension and generally tosimplify the construction and reduce the number of working parts to aminimum.

To the accomplishment of the aforesaid objects my invention consists inthe peculiar and novel construction, arrangement, and combination ofparts hereinafter described and then specifically pointed out in theclaims, reference being had to the accompanying drawings, which form apart of this specification.

In the accompanying drawings, in which similar ref erence-nu meralsindicate like parts in the different figures, Figure 1 is a frontelevation of my improved machine; Fig. 2, a side elevation looking fromthe left of Fig. 1, with certain parts in section at the line cc x ofFig. 1; Fig. 3, a section of a portion of Fig. 1 at the line y y; Fig.4:, an enlarged View of a portion of the winding-drum to illustrate thewire-clampingdevice; Fig. 5, a section of the same at the line a a ofFig. 4, and Fig. 6 an enlarged detail of the wireequalizing device andhereinafter described.

Referring to the figures, 1 is a metallic plate, which may be ofcast-iron, arranged to be secured to a heavy plank 2 by bolts 3, 4:, and5. On the right and left ends of the plate 1 and integral therewith areprojecting brackets 6 7 with their front faces in the same.

plane and parallel with the face of the plate 1, their adjacent endsdiverging from each other at the top and rounded at the bottom,

naled like-short shafts, the right arm 8 only being seen in Fig.2, whichshort shafts bear integral heads 9 and 10, having intheirfront faceslike channels to receive and fit the inner members 11 and 12 of thewire-clampingjaws,

which latter are retained therein by set-screws 13 and 14, respectively,and are hereinafter more fully described. the jaw 12 is a pivot 15,which bearsa nut in which runs a screw 16, secured against longitudinalmovement in a supporting-block 17 and provided with a hand-wheellS, bywhich it is turned. In the upper end of the jaw 11 is a like pivot 19,bearing a similar nut (not seen)in which runs a screw 20, having itsends revolubly secured in a block 21.

By the foregoing devices, the jaws 11 12 may be rocked on the shaft 8,and the corresponding shaft in' the right bracket, to bring the ends ofthe Wires into position for brazing as hereinafter described.

Through the lower ends of the jaws ll 12 are bolts 22 28, by which theouter jaws 24 25 are flexibly connected therewith and intermediateplates 26 27 retained between them. In the upper ends of the outer jaws24 25 are pivotally mounted cam-levers 28 29, arranged to bear againstthe upper ends of the jaws 11 12 as the levers are rocked downward andforce apart the upper ends of the inner and outer jaws, and thuscompress their lower ends. The adjacent faces of the outer and innerjaws and the interposed plates have corresponding oppositelydisposedgrooves 30 below the bolts 22 23 to form gripping devices for the wires,while the jaws 11 and 25, with the plate 27, have similar grooves 52above the bolt to permit the Wires from the opposite jaws to freely passto the winding-drum now to be described.

In the extension of the bracket 6 is a wrist 31, on which is revolublymounted aworm- Wheel 32, in which meshes a worm 33, running in supports34: 35 and turned by a hand-wheel 36. On the face of this worm-wheelis adrum 37, provided with a wire-gripping device constructed in thefollowing manner: In one side of the drum 37 is a recess (shown in Figs.4 and 5) in which is snugly fitted the clutch of In the upper end of Onthe periphery of the drum 37, and pref-- erably about opposite thewire-gripping device just described, is the tension-equalizing device,(shown in enlarged detail in Fig. 6,) and which consists of a post 43,having the upper end forked and in which is pivotally mounted a rockinglever 44, which stands transversely to the wires and has a centralupwardly-exten ding finger 45, preferably triangular in form, as shown,and two lateral upwardly-curved fingers 46.

To adapt this apparatus to operate when the wheel stands horizontally, Iprovide a two-armed bracket 47, secured to the plank 1 and having acentral cylindrical part 48 with an internal longitudinal screw-threadedopening in which runs a screw 49, operated by a hand-wheel 50 andbearing at its outer end a revolubly-mounted fork 51 to engage andsupport the wheel-felly.

In operation when it is intended to have the wheel stand verticallyduring the setting of the tire the wheel is placed against the plank 2,with the felly 53 resting in the fork '51, and adjusted in properrelation to the clamping-jaws by the hand-wheel 50 and screw 49, so thatthe jaws 11 12, with their oppositely-disposed members, will enter thechannel of the metallic tire 54. The rubber tire 55 is then placed inthe channeled tire 54 and the wiresfrom its right end secured in theright clamping-jaws by rocking down the lever 29. The wires from theopposite end of the rubber tire are then passed freely between the leftjaws, through the opening formed by the grooves 52, over the oppositelateral fingers 46 of the rocking lever 44, to and into the clutch inthe drum 37 on oppositesides of the wedge 41, which by a slight pushforward clamps them. To insure this clamping, the sides of the channel39 in the cylinder 38 may be slightly grooved to more securely hold thewire, and the sides of the wedge 41 may be corrugated where greattension is required. The drum 37 is then turned, by meansof the wormwheel 32 and worm 33, to wind the wires thereon until sufficient tensionhas been secured. In this portion of the process the rocking lever 44performs an important function in this that the wire having the greatesttension will bear down the end of the lever over which it passes, andthus raise and neoessarily increase the tension of the other until thetension on each is equal. When the desired tension has been secured, theleft jaws are closed upon them and the wires cut at such distance aswill permit sufiicient length for lapping and brazing. In this processthe clamping-jaws also perform the function not only of holding thewires preparatory to and during the process of brazing, but of assistingin regulating their direction, so that their point of union may beperipheral to the line they occupy about the wheel.

The operation just described refers to the process where the wheelstands wholly or nearly vertical; but the same process is used where theplank 1 and the wheel lie horizon tally, excepting that in such casesthe bracket 47, screw 49, and their associated parts are not needed.

Having thus described my invention, what I claim is 1. In arubber-tire-setting machinehaving gripping devices for holding the wiresfor brazing and a winding-drum to draw said wires, and means for turningsaid drum, of a regulating device to equalize the tension of said wireslocated between said drum and gripping device consisting of a pivotedlever having its opposite arms arranged to sustain the wires,substantially as shown and described.

2. An improved rubber-tire-setting machine consisting of a metallicplate having opposite offset brackets with their faces in the same planeand parallel with the face of said plate, with wire-grip ping devicespivotally mounted in said brackets, means for rocking said devices ontheir pivots, a winding-drum pro- 'vided with clutch mechanism to graspsaid wires and a pivoted lever interposed between said drum and grippingdevices having opposite arms to support said wires, and a wormwheel andworm to turn said drum, substantially as shown and described.

In testimony that I claim the above I hereunto set my hand in thepresence of two subscribing witnesses.
